I can’t find this Merc prop listed anywhere and all it has is 48-83485-C-18 stamped on the hub. It might be for an Alpha drive but not sure. The pitch isn’t stamped anywhere on the hub either. 😕
Thanks for the info. I just picked it up and it’s now mounted on my Alpha One Gen II. It’s larger diameter than the 19 and 21 inch three blade props I use but it should work.
